[jboss-jira] [JBoss JIRA] (AS7-6254) Memory leak caused by retained connection ids in RemotingConnectorServer superclass

[Taras Tielkes (JIRA)]

     [ https://issues.jboss.org/browse/AS7-6254?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Taras Tielkes updated AS7-6254:
-------------------------------

    Description: 
We're running 7.1.1, with a patch applied for REMJMX-45 to limit the worst leaks coming from the JMX subsystem.

However, even with this patch applied we can only survive for a few days in a production-like scenario.

It seems that {{org.jboss.remotingjmx.RemotingConnectorServer}} never calls the {{connectionClosed()}}/{{connectionFailed()}} methods in its superclass.
As such, the connection ids that are stored in the field {{javax.management.remote.JMXConnectorServer#connectionIds}} are never released.

Given sufficient connections made to a running instance of 7.1.1 (for example, various monitoring tools), an out-of-memory end-state is inevitable.
